[12] JDK-7124285: Nothing heard from VoiceOver regarding the status of the progress bar

[shashidhara . veerabhadraiah]

Hi All, Please review a swingset fix for the below bug.
Bug: https://bugs.openjdk.java.net/browse/JDK-7124285

Fix: http://cr.openjdk.java.net/~sveerabhadra/7124285/webrev.00/

Problem: The JProgressBar component used in the swingset demo was not 
focusable and once it is turned on, now the progress status is getting 
narrated via the voice over.

Thanks and regards,
Shashi
